MD5 errors after uploading

Development Tools IDE 1.x
1

Hi all
I use 2 same heltec lora esp32 boards. Both with factory code. One board I uploaded using arduino web editor and later using arduino IDE installed on the macbook air. Works fine. I have tried to upload same code to another board, which still have factory code, and i got this error. Do I have to reset or erase somehow factory code? Or what?
Please help.
Thanks in advance

I found solution. Just type in terminal: esptool.py --port write_flash_status --non-volatile 0
